Abstract

In 2018, tuna production in D.I. Yogyakarta reached 371.66 tons, of which 75-82% were captured using the handline. The dominance of the tuna caught has led to the development of the handline that highly dependent on the potential of tuna resources. Investment prospects are also important because they become a reference for investors in investing in the tuna handline busineses. This study aims to analyze the potential of tuna fish resources including the spread of its fishing ground and analyze the feasibility of developing tuna handline buseneses in the waters of D.I. Yogyakarta. The data of this study were analyzed using the Schaefer model, mapping using geographic information system (GIS), and investment feasibility analysis. The potential of tuna fish production in the waters of D.I. Yogyakarta reached 628,53 tons/year, while the average production was 427,32 tons/year, so it is still prospective to be developed. Potential fishing ground for tuna handline was spreaded in the waters of Bantul Regency until the western border waters of Gunung Kidul Regency, and in the eastern waters of Gunung Kidul Regency. The tuna handline was also prospective to be developed its investment in D.I. Yogyakarta. The value of NPV, IRR, ROI, and B/C ratio of tuna handline were very good, i.e., IDR 425,121,064; 36.49%; 9,36; and 1.22 respectively. Keywords: fish resource, geographic information system, investment, the waters of D.I. Yogyakarta, tuna handline

Abstract

This study aims to assess the status of the sustainability and the factors supporting or hindering the livelihoods of tuna hand line fishermen on Buru Island which includes Buru and south Buru regency. This study applied the FLIRES (Fisheries Livelihood Resilience) Check instrument which combines the principles of the Sustainable Livelihood Analysis (SLA) with the RAPFISH approach. Data collection started from March to August 2020, through observations and interviews of tuna hand line fishermen respondents in seventeen coastal villages in Buru and South Buru. Data were analyzed using RAPFISH which includes multidimensional scaling (MDS), leverage and monte carlo analysis. The results obtained, some index values of livelihood’s sustainability of tuna hand line fishers in the research location, in six fields, namely natural, human, physical, financial, social and instituional, ranged from 43.11 to 69.43, which indicate that the status of livelihoods in Buru is less sustainable in the natural field, while in South Buru it less sustainable in the human, physical and financial fields. Meanwhile, other fields indicate a fairly sustainable status. This study also identified there were 17 sensitive attributes from all fields that were supporting or hindering factors for the livelihood of tuna hand line fishermen in the research location. This finding has been expected to become a reference in improving the sustainability of the livelihoods of tuna hand line fishermen on Buru Island.

Abstract

The study was conducted from August to September 2024 at the seaweed cultivation location in Kaiely Bay, with sampling at three observation stations. The method used was a survey with a laboratory approach. The parameters analyzed included phytoplankton abundance, chlorophyll-a content, and identification of pests and diseases in seaweed. The data obtained were analyzed descriptively. The results of the study showed that the abundance of phytoplankton at the three research stations was very high (eutrophic) with the highest value at Station 2 (8,133,333.33 cells/L) and the lowest at Station 3 (6,043,333.33 cells/L). Chlorophyll-a at all stations was in the eutrophic category with the highest concentration at Station 2 (0.00137 mg/L). The types of pests found at all stations were chicken fish, rabbitfish, and turtles. There were two types of bacteria found, namely station 1 pathogenic bacteria Pseudomonas aeruginosa, station 2 and station 3 types of Vibrio. Thallus morphology at station 1 was: gouging and stripping, station 2 was stripping, tip-nipping and ice-ice and station 3 was gouging, stripping, tip-nipping, and ice-ice.
